With high demands from many industries, ATS offers electrical resistance heat treatment services throughout the Southeast. This treatment may benefit many of our current and potential new clients who are in the process of receiving other ATS engineering, testing, and nondestructive inspection services.

Heat Treatment Objective & Method

Objective:

Heat Treating is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product’s shape. Noted benefits to this treatment are increasing the strength of material or achieving certain manufacturability objectives like improved machining, improved formability, or restore ductility after a cold working operation. In addition to the manufacturing benefits, many industries may rely on this process for better product performance due to increase strength and other desirable physical characteristics.

Why Pre & Post Weld Heat Treatment (PWHT)?

Benefits for Preheating:

The goal of preheating is to reduce the cooling rate of the base metal and deposited weld metal.

Method:

Uniform heat penetration

Maintaining specific minimum temperatures

Less downtime with components always ready to weld

Welder productivity for faster turnarounds

Eliminates manual preheat example "rosebuds"

Eliminates any open flames reducing a major SAFETY issue

Recordable documentation of preheat

Benefits for Post Weld Heat Treatment (PWHT):

Post Weld Heat Treatment or Stress Relief is a crucial step in maximizing the life of process equipment. PWHT tempers the metal and reduces tensile stresses, minimizing the risk of brittle fracture, stress and corrosion cracking and metal fatigue. This is especially important for equipment used in harsh service environments for examples Refiners and Utility Industries.
